Metal after Victory

IF ONLY SEQUEL

A warship had been detected in our universe, and the signal is moving fast. What we didn't know was that a ancient alien race was the signal, and that they weren't just exiled to another planet years ago, but they were exiled to another dimension.
Our world does not have just one universe.

But, us Autobots couldn't destroy them by mere force, and with just us few here. We will have to team up with someone we despise, and someone we have to learn to respect.
But a task has been given to me, and i have to make the most drastic decision of my life. Along with a surprise happening at the same time.

To destroy our new enemies, it will take me, Optimus, and Megatron -of all people- to protect our world.

But will everything work out as planned?
